【问题描述】：

问题： 我创建了一个自定义配置文件对象，如 Joel here 所述。然后我使用 Jeremy 的方法 (here) 来扩展自定义配置文件以允许我使用生成用户并设置这些值。然后我创建了一个 ViewModel 来显示会员信息和个人资料信息，以便用户可以更新他们的会员信息（电子邮件）和个人资料信息。 **视图显示了我在视图中更新信息中输入的所有字段，然后点击保存，出现如下错误

System.Configuration.SettingsPropertyNotFoundException：找不到设置属性“FirstName”。 **

这是我的自定义配置文件对象（模型）：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Web.Profile;
using System.Web.Security;


namespace NDAC.Models

    public class ProfileInformation : ProfileBase
    
        static public ProfileInformation CurrentUser
        
            get
            
                if (Membership.GetUser() != null)
                
                     return (ProfileInformation)(ProfileBase.Create(Membership.GetUser().UserName));
                
                else
                
                    return null;
                
            
        

        public virtual string FirstName 
            get
            

                return ((string)(base["FirstName"]));
            
            set 
            
                base["FirstName"] = value; Save();
             
        
        public virtual string LastName 
            get 
            
                return ((string)(base["LastName"]));
            
            set 
            
                base["LastName"] = value; Save();
            
        
        public string Street 
        
            get 
            
                return ((string)(base["Street"]));
            
            set 
            
                base["Street"] = value; Save();
            
        
        public string Street2 
         
            get 
            
                return ((string)(base["Street2"]));
            
            set 
            
                base["Street2"] = value; Save();
            
        
        public string City 
        
            get 
            
                return ((string)(base["City"]));
            
            set 
            
                base["City"] = value; Save();
            
        
        public string State 
        
            get 
            
                return ((string)(base["State"]));
            
            set 
            
                base["State"] = value; Save();
            
        
        public string ZipCode 
        
            get 
            
                return ((string)(base["ZipCode"]));
            
            set 
            
                base["ZipCode"] = value; Save();
            
        
        public string PhoneNumber 
        
            get 
            
                return ((string)(base["PhoneNumber"]));
            
            set 
            
                base["PhoneNumber"] = value; Save();
            
        
        public string SemesterID 
        
            get 
            
                return ((string)(base["SemesterID"]));
            
            set 
            
                base["SemesterID"] = value; Save();
            
        

        static public  ProfileInformation GetProfile(string username)
        
            return Create(username) as ProfileInformation;
        

        internal static ProfileInformation NewUser
        
            get  return System.Web.HttpContext.Current.Profile as ProfileInformation; 
        

    

这里是 UserProfile 获取方法：

[Authorize]
        public ActionResult UserProfile()
        
            string id = User.Identity.Name.ToString();
            MembershipUser user = Membership.GetUser(id);

           var model = new UserViewModel();

            UserInformation userInf = new UserInformation();
            userInf.Username = user.UserName;
            userInf.Email = user.Email;

            ProfileInformation currentProfile = ProfileInformation.GetProfile(user.UserName);

            model.Profile = currentProfile;
            model.UserInf = userInf;    

            return View(model);

        

如您所见，我正在使用视图模型来显示视图。 视图模型是这样的：

 public class UserViewModel
    

        public UserInformation UserInf get; set; 
        public ProfileInformation Profile  get; set; 


    

最后更新 UserProfile 的 HttpPost 方法是：

[Authorize]
        [HttpPost]
        public ActionResult UserProfile(UserViewModel model)
        
            ProfileInformation currentProfile = ProfileInformation.GetProfile(User.Identity.Name.ToString());

            ProfileInformation.CurrentUser.FirstName = model.Profile.FirstName;
            currentProfile.LastName = model.Profile.LastName;
            currentProfile.Street = model.Profile.Street;
            currentProfile.Street2 = model.Profile.Street2;
            currentProfile.City = model.Profile.City;
            currentProfile.State= model.Profile.State;
            currentProfile.ZipCode = model.Profile.ZipCode;
            currentProfile.PhoneNumber = model.Profile.PhoneNumber;
            currentProfile.Save();

            MembershipUser user = Membership.GetUser(User.Identity.Name.ToString());
            user.Email = model.UserInf.Email;
            Membership.UpdateUser(user);


            TempData["SuccessMessage"] = "Your Profile information has been saved";
            ViewBag.Title = "My Profile";
            return RedirectToAction("ProfileUpdated");
        

问题是我无法弄清楚错误来自哪里。表单呈现我输入有效信息，然后我被告知“未找到设置属性 'FirstName'。”就像 UserViewModel 正在尝试更新 ProfileInformation.cs （自定义配置文件对象），但它说它找不到对象......我想这是因为它没有要更新的配置文件......但我在发布之前无法解决错误……太令人沮丧了！任何帮助将不胜感激！！！感谢您抽出宝贵时间查看此内容。

我还将向您介绍我的 Register 方法，该方法成功地使用了自定义 Profile 对象，甚至将 name 属性更新为“ScoobyDoo”以进行测试:)

[HttpPost]
        public ActionResult Register(RegisterModel model)
        
            if (ModelState.IsValid)
            
                // Attempt to register the user
                MembershipCreateStatus createStatus = MembershipService.CreateUser(model.UserName, model.Password, model.Email, model.SecretQuestion, model.SecretAnswer);

                if (createStatus == MembershipCreateStatus.Success)
                

                    FormsService.SignIn(model.UserName, false /* createPersistentCookie */);
                    Roles.AddUserToRole(model.UserName, "Student");
                    ProfileInformation.NewUser.Initialize(model.UserName, true);
                    ProfileInformation.NewUser.Save();

                    string currentSemesterID = CurrentSemester;
                    ProfileInformation profile = ProfileInformation.GetProfile(model.UserName);
                    profile.SemesterID = currentSemesterID;
                    profile.FirstName = "ScoobyDoo";

                    return RedirectToAction("Index", "Home");
                
                else
                
                    ModelState.AddModelError("", AccountValidation.ErrorCodeToString(createStatus));
                
            

            // If we got this far, something failed, redisplay form
            ViewBag.PasswordLength = MembershipService.MinPasswordLength;
            return View(model);
        

【参考方案1】：

您可能需要提供您自己的配置文件实现...如果您已经这样做了，您是否已将自定义提供程序类型添加到您的“web.config”中？

例子：

<profile defaultProvider="TableProfileProvider" enabled="true" inherits="YourNamespace.YourClass, YourNamespace">

很棒的 MSDN 文章 here、here 和 here。

我希望这些能帮助您顺利上路！
